Representative St. Fleur was one of the most active supporters of John Kerry's presidential bid, often traveling to Florida to do outreach on his behalf.

Representative St. Fleur was appointed Vice-Chair of the powerful Ways and Means Committee by House Speaker Salvatore DiMasi, a leadership position that has tremendous influence in the budget process.

[4] St. Fleur emigrated from Haiti[5] as a child and attended the University of Massachusetts Amherst and Boston College Law School.

In 1999, she became the first Haitian immigrant to hold public office in Massachusetts by winning a special election to succeed Charlotte Golar Richie.

[4] The issue of St. Fleur's withdrawal received additional media attention when it was mentioned in an exchange between Reilly and rivals for the Democratic nomination Deval Patrick and Chris Gabrieli during the gubernatorial debate on September 7, 2006.

In February 2010 she announced that she would not run for reelection and in April 2010 she accepted a job as director of intergovernmental relations for the City of Boston.
